It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)
Answer:
a) 3x + y = -5 & b) y = 1/3 ( 21- 9x )
Step-by-step explanation:
a)
3x + y = -5
y = -3x -5
b)
y = 1/3 ( 21 - 9x)
y = -3x + 7
y = 3x + 2.5
the slop is to be same in the parallel lines. slop means m in ( y = mx + c )
so a) & b) are parallel lines. since their m is -3 .
Answer:

Step-by-step explanation:
He earns 12.50 each hour and has worked 34 hours in total that makes :
12.50 × 34 = 425
Answer:
radius = 6; diameter = 12; circumference = 12pi; area = 36pi
Step-by-step explanation:
Diameter is given,
radius is have of diameter
circumference = pi*d
area = pi*r^2
Given:
There are given that the polynomial:
Explanation:
According to the concept, trinomial is three terms, and binomial means two terms.
And,
When the degree of any polynomial is 2, then it represents quadratic, when the degree is 3, it represents cubic, when the degree is 4, then it represents quartic, and when the degree is 5, then it represents quintic.
Now,
From the equation:
In the above equation, there are only two parts and they have degree 4.
So, the given terms represent quartic binomial.
Final answer:
Hence, the correct option is C.
